We're dividing 659274 by 21 
We want to figure out the number of times 659274 can be divided by 21.

On to step 1:
If we divide 6 by 21, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 21

Let's proceed to step 2:
21 can be fit into 65 3 times, resulting in a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 63 from 65 and we're left with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 21

On to step 3:
29 divided by 21 is 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 31.0
Subtracting 21 from 29 leaves us with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 21

On to step 4:
82 divided by 21 is 3 with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 313.0
Subtracting 63 from 82 leaves us with 19.
Take the next digit (7) from the dividend and append it to 19, then repeat: 197 / 21

Step 5:
21 goes into 197 9 times with a remainder of 8.
The next digit of our result is 9. 
Result so far: 3139.0
The remainder is 8 after subtracting 189 from 197.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 21

Moving on to step 6:
When dividing 84 by 21, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 31394.0
Subtract 84 from 84 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
21 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 31394.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
If we divide 0 by 21, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 31394.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 31394.0 with a remaining 0.0.
